It's been a long time coming, but here it is. Changes so far relative
to v2.1.1:
o ColData, const_string, and SQLString can now be constructed
with an explicit length parameter. Furthermore, Query
class's execute(), store() and use() call chains terminate
in a version taking an explicit length parameter, instead
of one taking a simple C string. Together, this means
that it's now possible to handle data from the SQL server
containing nulls. The library is almost certainly not yet
capable of handling embedded nulls in all cases, but this
is a big first step towards that.
o Can now construct a DateTime object from a time_t. Patch by
Korolyov Ilya.
o Changed the way we're handling exported functions in the
Windows DLL case so that it works more reliably under MinGW.
o Added proper copy semantics to Connection, so that you get a
new connection with the same parameters, not just a bitwise
copy of the object.
o Added exrun shell script and exrun.bat files to distribution,
to avoid linkage errors when running the examples while
you have an older version of MySQL++ still installed.
o Using an explicitly thread-safe variant of localtime() where
one is available.
o Removed ListInsert template from myset.h. This wasn't used
within the library, and was never documented, so I'm betting
that no one actually uses it.
o Result::copy() was not copying the exception flag in
all cases. Fix by Steven Van Ingelgem.
o Renamed MYSQLPP_LIB_VERSION to MYSQLPP_HEADER_VERSION, as
what it really encodes is the version number in the mysql++.h
file you're using, not the actual library version number.
o Added mysqlpp::get_library_version(), which returns the
library version number at build time. Between this and
the header version constant, you can check that you're not
mixing MySQL++ header and library versions.
o resetdb example uses these new version number affordances to
double-check that you're not mixing libraries and headers
from different versions. This happens easily unless you
take care of it (such as by using exrun) when you have one
version of MySQL++ installed and you're trying to build and
test a new version without blowing away the old one first
or overwriting it.
o No longer using recursive Makefiles on Unixy platforms
or split lib + examples project files on VC++. Everything is
handled by a single top-level Makefile or project file, which
is simpler for the end user, and makes better dependency
management possible.
o When looking for the MySQL C library on systems using
autoconf, looking in .../lib64 wherever we are also looking
in .../lib.
o RPM build process no longer depends on Bakefile. It means
you have to build the examples when building an RPM even
though they're never used within the RPM, but it's a better
tradeoff in my opinion.
o Updated include and library paths on Windows to reflect
changes in the most recent MySQL installers.
o Merged lib/defs.h and lib/platform.h into new file,
lib/common.h. Just cleans up the library internals.
o Fixed build errors on Windows due to recent changes in MySQL.
o Fixed a few memory leaks and double-deletes in Query class.
o Fixed compatibility with STLPort's string implementation.
Patch by dengxy at cse.buaa.edu.cn.
o Fixed a compatibility problem between Set<> template and
SSQLS. Patch by Korolyov Ilya.
o Fixed build bug in SQLQueryParms due to a character
signedness issue on PowerPC with GCC. Patch by Michael
Hanselmann.
o ~Transaction() can no longer throw exceptions. It'll just
quietly eat them, to avoid program termination. Fix
suggested by Alex Burton.
o Fixed thread safety testing in autoconf case, accidentally
broken during v2.1.0 development cycle.
o Using Doxygen 1.5.1 to generate documentation.
You can download the latest beta from http://tangentsoft.net/mysql++/ in
many forms, or you can check out the absolute brandest newest from svn.
I hope to get this release finalized within a week, so if you have
problems with it, please let me know soon.
